Imaging Apparatus Housing Thermal Conductive Filler Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatus housings made from resin with thermal conductive fillers do not effectively transfer heat from internal components to the exterior, limiting radiation performance due to filler alignment issues during molding.
Innovation Solution
The housing is designed with thermal conductive fillers aligned in a specific manner, where the longitudinal direction of fillers in one part faces the exterior and another part faces the interior, facilitating efficient heat transfer from internal heating elements to the outside through the housing material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If thermal conductive fillers are randomly distributed in the housing resin, then the housing structure is simple and easy to manufacture, but the heat transfer performance from interior to exterior is insufficient
Solution Approach 1:
The patent applies local quality by differentiating filler orientation in different spatial regions of the housing. Fillers in the first part (facing exterior) are oriented to facilitate heat transfer to the exterior, while fillers in the second part (facing interior) are oriented differently to optimize heat collection from internal components. This regional differentiation of filler properties resolves the contradiction by optimizing heat transfer performance in specific locations without requiring complete reorientation of all fillers.
Solution Approach 2:
The housing is segmented into at least two distinct parts: a first part facing the exterior and a second part facing the interior. Each segment has fillers oriented according to its specific thermal management requirements. This segmentation allows the patent to achieve optimized heat transfer performance in critical regions while maintaining manufacturing feasibility through region-specific rather than globally complex filler alignment.
2Reliability
If fillers are aligned to maximize heat transfer to exterior, then radiation performance improves, but manufacturing precision requirements increase
Solution Approach 1:
The patent implements local quality by specifying that only fillers in the first part (exterior-facing) need to be oriented toward the exterior for optimal heat transfer, while fillers in the second part (interior-facing) have different orientation requirements. This localized approach to filler orientation reduces the overall manufacturing precision burden compared to requiring uniform high-precision alignment throughout the entire housing, while still achieving reliable radiation performance in the critical exterior region.

AI summary
An imaging apparatus comprises a housing which includes a resin containing a plurality of fillers, each filler having a longitudinal direction, an imaging optical system fixed to an opening provided in the housing, and an imaging device stored in the housing and configured to capture an object image formed through the imaging optical system. the longitudinal directions of first fillers in a first part of the housing facing an exterior of the housing are positioned along a direction from the inside to the outside of the housing, and the longitudinal directions of second fillers in a second part of housing facing an interior of the housing are positioned along an interior wall of the housing.
